In another blow to the global ambitions of Chinese firms, Huawei Technologies Co.’s planned deal with U.S. carrier AT&T Inc. to sell its smartphones in the United States also fell apart because of security concerns, people with knowledge of the matter said Wednesday.

The failed deals come as the United States considers several new tariff moves in the coming weeks, including broad restrictions on steel and aluminum imports and punitive actions against China.

“But my base case is that we will see more trade frictions this year than last, but that it’s not going to lead to a significant decline in real exports from China.”

An editorial in China Daily on Thursday blamed the termination of the Huawei-AT&T deal on political pressure instead of business considerations, and said this threatened the kind of win-win relationship China sought.

“This is not the first time U.S. politicians have stooped to mudslinging to prevent the entry of Chinese high-tech companies into the U.S. market on the pretext they pose national security threats,” it said.

The U.S. Government’s criticism of China’s tightly controlled economy and restrictions on foreign investment rang hollow, it added. (SD-Agencies)
